WINTHROP — A local woman involved in a crash that killed her husband Thursday continues to be treated at a Lewiston hospital.

Patricia St. Laurent, 74, was in critical condition at Central Maine Medical Center, according to a hospital representative. No other details of her condition were provided, though updates posted by family members on the social network site Facebook indicate St. Laurent suffered multiple injuries and is being treated in the intensive care unit.

St. Laurent was flown to the hospital Thursday morning after the van she was riding in was hit from behind by a box truck on U.S. Route 202. St. Laurent’s husband, 80-year-old Napoleon Richard St. Laurent, was pronounced dead at the scene.

The driver of the box truck, Jeffrey Ray, 44, of Scarborough, also was flown to CMMC after the crash. He was no longer at the hospital Friday afternoon, according to the representative.

The crash occurred shortly before 9 a.m. as the St. Laurents’ 1996 Ford E-150 van was stopped in the eastbound lane waiting to make a left turn onto Royal Street. Ray, driving a 2007 Mitsubishi box truck east on U.S. 202, hit the van from behind, Young said. Winthrop Police Chief Joseph Young said the impact pushed both vehicles into the right-side guard rail and down the road before coming to rest against the guardrail.

Young said neither of the St. Laurents was wearing a seat belt. Investigators are still trying to determine if Ray was belted in.

The section of U.S. 202 was closed for about four hours as traffic was diverted onto Main Street.

The van, owned by JA & Sons, an automotive repair business in Winthrop that St. Laurent owned with his son, was totaled. The box truck, owned by Lewiston-based Pure-Stat Technologies, also was destroyed.
